“…Owing to the long-term endeavors of the groups of Maatta, [14] Errington, [15] and Proust, [16] terminally substituted mono-and even multifunctionalized organoimido derivatives of POMs can now be conveniently prepared with various imido-releasing reagents, including phosphinimines, isocyanates, and aromatic amines. [14][15][16][17][18] In principle, the bridging oxygen atoms in POMs can also be replaced by organoimido ligands; however, such a bridging organoimido-substituted POM has not been obtained to date.…”

Building bridges: Two arylimido derivatives of hexamolybdate, containing unprecedented bridging imido ligands, have been synthesized and structurally characterized. Their 1H NMR and UV/Vis spectra distinguish them from related terminally coordinated derivatives. Such compounds extend the range of organoimido polyoxometalate coordination chemistry, providing insight into the mechanism of oxo metathesis in the Lindqvist polymolybdate.

Following the pioneering investigations by Zubieta and co-workers, [46] this family of polyanions has been extended by Errington, Maatta, Proust, Peng and Wei groups [32] and now includes nitrosyl, [47][48][49] hydrazido, [50] diazenido [46,[51][52] nitrido [50] and imido [53][54][55][56][57][58] derivatives. One diazoalkane derivative has been also reported by Maatta and coworkers.…”

The electroactive benzothiazole hydrazone AMBTH-H(2), a new member of the 2,2'-azino-bis(N-alkylbenzothiazole) family, was synthesised in a five-step procedure and characterised by using X-ray diffraction along with two intermediates and the N-methylbenzothiazole hydrazone MBTH-H(2). Both AMBTH-H(2) and MBTH-H(2) were coupled to [Mo(6)O(19)](2-) in acetonitrile in the presence of dicyclohexylcarbodiimide and dimethylaminopyridine to give two new diazoalkane-hexamolybdates, which were isolated as tetrabutylammonium salts and characterised by using IR, UV/Vis and NMR spectroscopies, cyclic voltammetry and, for one of them, X-ray diffraction. The packing arrangement molecules in crystals of AMBTH-H(2), the redox features of the AMBTH-hexamolybdate hybrid together with a good electronic communication between the organic pi system and the molybdenum centres make these compounds very promising blocks for the synthesis of conducting molecular materials.

Due to the interaction between one H atom in the aryl group and an O atom of a symmetry-related hexamolybdate cluster, the anions form centrosymmetric dimers in the crystal structure. Weak C-HÁ Á ÁO contacts are observed between the cations and anions. Unresolved disorder in some of the butyl chains of the ammonium cation is noted. Related literature
